Question 1 options:
given: triangle abc. the ratio of angles angles a: b: c is 5: 4: 3.

find the measures of angle a, angle b and angle c.

measure of angle a =

degrees.

measure of angle b =

degrees.

measure of angle c =

degrees.

Step-by-step explanation:

The sum of ratio units is 5+4+3 = 12. Comparing that to the sum of angles in a triangle, 180°, you see that each ratio unit must stand for 180/12 = 15 degrees.

Multiply the ratio of angles by 15° and you get the actual angles:

  A : B : C = 75° : 60° : 45°

Angle A is 75°, Angle B is 60°, Angle C is 45°.
